+* **prodash**
+  * finish transitioning to futures-lite to get rid of futures-util dependency to reduce compile times
+* **gitoxide performance**
+  * [ ] @joshtriplett writes: "Regarding decompression performance, try replacing miniz_oxide with a better zlib decoder. Build with libz-sys, and then try substituting zlib-ng built with --zlib-compat. (I'm working on making that easier.) That should substantially improve decompression."
+    * potential [savings: MASSIVE](https://github.com/Byron/gitoxide/issues/1#issuecomment-672626465) 
+    * Note that this should only be feature toggled. Using any of the above would replace a pure Rust implementation, which we would always like to keep as an option for those who want maximum safety.
+  * [ ] Add '--chunk|batch-size' flag to `pack-verify` and `index-from-pack` to allow tuning sizes for large amounts of cores
+    * potential savings: medium
+  * [ ] Add more control over the amount of memory used for the `less-memory` algorithm of `pack-verify` to increase cache hit rate at the cost of memory.
+    Note that depending on this setting, it might not be needed anymore to iterated over sorted offsets, freeing 150MB of memory in the process
+    that could be used for the improved cache. With the current cache and no sorted offsets, the time nearly triples.
+  * [ ] _progress measuring costs when using 96 cores_ (see [this comment][josh-aug-12])
+    * potential savings: low
 * **criner**
   * [ ] switch to `isahc`
     seems to allow async-reading of bodies, allowing to get rid of reqwest and tokio. Redirect is configurable.
 * **quick-error** update
   * We need a new release soon with the latest updates to get rid of our git dependency. Until then we can't release.
